To all 'whom t may concern:

Be it known that I, JAMES A. ScRoGGiN, a citizen of-the United States, and a resident of Little Rock, in the county of Pulaski and State of Arkansas, have invented a certain new and useful Improvement V-inl lVlusic-4 LeafV Holders, of which the followingy 1s aj the spring for swinging the same.

speciiication. One of the principal objects Vof the invention is to provide an improved music leaf holder, of booklike form, which may be used in holding sheets of music of various sizes, the device being of such nature that it may be mechanically operated for turning the sheets of music one at a time, without the necessity of the operator or'musician removing his hand from the instrumentvhe is playing.

Another object of the invention is to provide an improved -method of constructing, mounting, and operating a music sheet holder. I f I A further object of the invention is to provide an improved music sheet holder having a novelmeans of releasing the frames which support the music sheets.

Still another object of the invention is tok provide an improved device of the class described which will be extremely simple, durable, efficient in operation, and inexpensive to manufacture.

Vfith these and other objects in view which will become apparent 'as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which like characters of reference indicate like parts throughout the several figures, of which l v p l Figure 1 represents a face view of the device. f

In carrying out myinvention I provide l a casing-consisting of flat leaves 5 and 6 hingedly connected at their near ends to a transversely curved back 7in such manner that the leaves lmay be swung one relatively to the other in order to'open the casingv outwardly in the form of a book in themanner indicated in dotted lines in Fig. 4. The leaf 5 is provided at its top and bottom edges with upwardly extending` walls 8, and along its outer longitudinal edge with a hinged wall 9, which may be shifted from the vertical position assumed vwhen the casing is in closed position', to the downwardly extending dotted line position indicated in Fig. 4,-whereby` to retain the leaf 5 in aplane substantially parallel with the plane in; which the leaf 6 lies when the casing is in open p0- sition. This leaf 6is provided along its outer I longitudinal edge with a downwardly eX- tending lip`-10 which may enga-ge over the upper` edge of wall 9 when the casing is closed, as -indicated in Fig. 4.

spaced above .the leaf'5, is a rod 11, upon 'V which the frames Vto beherei'nafter described, may swing as a pivot. 4Rotatably mounted upon this rodare thev L-shapedr arms 12. To each of thelatter is connected one end of a coiled spring 13, 4which surrounds the rod and whose opposite end is suitably connected to said rod.V The outer portionsof arms 12 extend in parallel relation with the rod, and are provided with' squared recesses for the reception of lthe downturned squareends 14 of arms 15 provided each upon one of the rectangular Set screws or other suitable means 17 as indicated clearly in Fig. 9 may be used if desired, to prevent accidental disengagement of the arms 15 and v12. The frames 16 are preferably rectangular in shape, and are preferably made of thin, j light strong steel or aluminum or other 1 of the frame as at 19, inorder to slid-ably engage said end bars. These bars 18niay be moved toward and away from each other to accommodate sheets of musicl of'various widths.' At intervals bars 1S are punched or stamped whereby to forni spring Yfingers V20 extending alternately on opposite sides of the bars, and projecting toward their inner edges, whereby sheets of music may be engaged beneath theseV spring fingers and on Opposite sides of said bars. n this manner, each of the frames 1G Vcarries if necessary two sheets of music, one sheet d'islgiosed upon each side of the frame. The bars 18 may be taken ofi.- of or put upon the frame lb by slipping them in the desired direction along the upper and lower bars of said frame.

The frames 16 are provided on their outer edges and adjacent their upper corners with the retaining lugs 21 preferably formed integrally'with said frames. These'lugs are adapted to be normally engaged by the-releasing mechanism to be hereinafter de scribed, `whereby to maintain said frames upon the right hand sideV of the device.

This releasing mechanism includes a guide bar or rod 22 extending between the walls 8 of' leaf 5 and in parallel relation with and'V slightly spaced from the frames 16. A sec-r tional slide consisting of a rack bar 23 and lower sections 24C is provided. This rack bar has a channel formed in its upper face into which the guide bar 22 lits, and belts or ties V25 bridge the' channel above they guide 22" in order to slidably retain said rack bar in po Ysition.V Depending flanges 26 having inwardly projecting lips 27 extend along the longitudinal edges of the rack bar 25. Be-

tween these flanges 26 and retained against the rack bar through the action of the lips Y 27, are disposed the lower sections 24C of the releasing device.

The holding lugs 21 are arranged with respect to vthe releasing device in series of three. That is, the holding lugs of the topinost second and third lower frames lie in a. single plane, while the lugs of the fourth,

lifth and sixth frames/lie in a plane below the' plane in which the first lugs lie, and spaced therefrom a distance substantially equal to Vthe thickness of one vf the lower sections 242 ofthe releasing mechanism. The arrangement whereby the lugs may be ar- W ranged in tiers is shown in Fig. 8, 'from an inspection of which it will be seen that the Vlug on the second lower frame occurs a distance from vthe upper edgeV of the frame Y plane spaced from that in which the rst tier lies.

Y The releasing device is of a width greater Y than the width of the'guide'22, and the outer ends of theV retaining lugs engage beneath the adjacent edge of the releasing device, but

Y do not underliey the guide bar. As indicated Y in Fig. 6, 'the first three lugs or the first tier ofV lugs, engage against the rack bar .3 while the next tier engages beneath the next sei-- tion of the releasing device Vand the third tier beneath the third section of the .rel asing device, and soon. The sections 2t are successively shorter than the rack bar 23 and shorter one than the other by a distance equa lto the lengtliofl one ofthe tiers of the retaining lugs. Each section of the slide or releasing member is thus adapted to control the release of one tier of holding lugs, Through the action of'means to be hereinafter described, the rac-k bar 23y rst is actuated step by stepV a distance each time equal to the length of one of the lugs, so that at first the upper tier of frames is released one at a time. As soon as the first tier is released a lug 4:7 carried on the under-surface of rack bar 23 and extending-'into a slot provided in the upper surface of the next lower section, engages the lower end of that slot so that the second section is taken up and the next tier'of frames successively released. This action continues,v the sections of the releasing device being successively operated, until the desired or entire number of casing, they lie on top of each other in the nia-nner shown, and as they are successively released and swung through the action of the springs 18 onto the opposite leaf, they againpile up in succession, one above the other.V It will be noted from Fig. 4 that the arms 12 Vare so shaped as to have their outer ends disposed in a plane coincident with the plane in which the frames to which they are connected lie. In Fig. l only siX of the frames have been illustrated, but it will be understood that obviously more frames may be used if desired, or a smaller number may be used without departing from the spirit of the invention. In Fig. 6 three sections of thel releasing device have been illustrated and nine of the retaining lugs have been indicated, so as to readily set forth the are rangement desired. No specific limitation is VVset upon the number of lugs which may be lll) Vwhich a piston 29 is 'by the foot of the musician,

arranged in each tier, since if desired two or more lugs may form one tier.

The mechanism for actuating the releasing means includes a cylinder 2S a suitable manner upon leaf 5 and within adapted to play. rI`his piston is provided with a stem 3() which extends cut through a closure 31 connected with the cylinder, and which is then bent outwardly aud returned as at 32 and hingedly connected as at with a detent or linger 3l adapted to engage with the teeth 35 provided on the floor of a channel formed in the outer edge of the rack bar 23. A coiled sp1-ing 36 arranged within the cylinder 28 bears at one end against the closure 31 and at its other end against piston 29, and normally retains said piston at the inner eX- tremity of its path of movement. A stop 37 disposed upon the piston stem 30 acts as a means for limiting the outward movement of said stem, and hence the movement of the 'lin ger 3ft longitudinally of the guide 22. A pneumatic bulb 33 communicates through a tube 39 with the cylinder 28 behind the piston 29, whereby when the bulb is compressed' the piston will be moved outwardly. This tube 39 extends through a suitable opening provided in the end wall 9, and the length of the tube occurring on the inner side of the wall, indicated in Fig. 1, is great enough to allow said wall to be swung into downward dotted line position shown in Fig. t. The pneumatic bulb may be made in any suitable shape or size to be readily operated or if preferable, by hand. yThe linger 34 is normally retained in engagement with the rack bar through the medium of a spring 41-0 interposed between the nger and the adjacent portion of the piston stem. rlhe finger, by riding in the channel, is prevented from becoming disengaged from the teeth. Y

Each time the bulb 38 is pressed, the piston 29 is forced outwardly until stop 37 strikes the closure 31, and thus the finger 34 is moved downwardly relatively to the guide 22 and carries with it the rack bar 23. The length of throw of the linger 3a is equal to the length of one of the lugs 21, so that the rack bar is thus successively moved downwardly step by step, whereby to release one of the frames each time the" bulb is actuated. Then all or the desired number of frames have been released, they may be manually turned to the rightv hand side of the casing, and the linger 3a may then be moved out of engagement with the rack bar 23 by means of a knob 4t2 formed on the Enger, and the latter may be raised to overlie the rack bar,

out of engagement with the teeth, while the rack is being moved upwardly. By moving the rack bar into its upper'position, the sections 24 of the releasing device will be returned to the position indicated in Fig. 6, by

fastened in reason of the engagement of the lugs 27 with the upper extremities of the channels in which they' play. `When this position of the bar has been attained, the finger 3 may again be moved to engage the teeth, and the device will be ready for operation.
